The present invention relates to a gravel spreader for use in road work and the like and has for its prime object to provide a boX like structure in which gravel may be placed so that the structure may be dragged along and the gravel will be spread in a predetermined manner.

Another very important object of the invention resides in the provision of a spreader of this nature with a spreading and grading cross beam mounted therein with adjusting means so that said means may be raised and lowered. I

A still further very important object of the invention resides in the provision of a gravel spreader of this nature which is exceedingly strong and durable, inexpensive to manufacture, and efiicient and reliable in use.

lVith the above and numerous other objects in view as will appear as the description procoeds, the invention resides in certain novel features of construction, and in the combina tion and arrangement of parts as will be hereinafter morefully described and claimed.

In the drawing:

Figure l is a top plan view of the gravel spreader embodying the features of my invention,

Figure 2 is a front elevation thereof.

Figure 3 is a side elevation thereof, and

Figure l is a vertical longitudinal section therethrough.

Referring to the drawing in detail it will be seen that the device comprises generally a pair of runners R with side walls A rising therefrom and a rear wall B which has adjustably associated therewith between the runners R a grading and spreading beam 0.

The runners Rare in thenature of elongated spaced parallel coextensive beams 5 the forward ends of which are beveled as indicated at 6 to incline upwardly and forwardly and strap arms 7 are secured to the under edges of the beams 5 and the forward beveled end 6 thereof.

Clevises 8 are secured to the beams and links 9 are secured to the clevises and connected together by a ring 10 so that suitable fastening means may be connected thereto for dragging the spreader along the road. A

cross bar 11 extends transversely across the forward portions of the beams 5 immediately in front of the walls A.

Each wall A comprises a pair of superposed vertical coplanar boards 12 and 14 connected on their outer sides by straps 15 and angle iron 16. The straps 15 are disposed adjacent the ends of the boards while the angle iron is disposed adjacent the center thereof. On the inner sides of the boards are secured together by a strap iron 18 which is extended at its lower end and secured to the adjacent beam 5 and by an angle iron 19 which is also extended at its bottom end and secured to the adjacent beam 5. y

The angle irons 19 aredisposed in spaced relation to the rear wall B.

The rear wall B comprises a cross bar with a board 21 rising therefrom and a. board 22 i is fixed to the front of the board 21 and extends upwardly from the beams 5. Brackets 23 are secured to the rear wall and have threaded thereto rods 24 vertically disposed and swivelly connected as at 25 with brackets 26 rising from the beam B and the upper ends of the rods 24 are in the form of cranks 27 so that by turning these cranks the rods will cause the beam B to be raised or lowered as may be desired. The bottom edge of the beam is arcuate as indicated at 28 and abowed blade 29 is secured thereto.

This beam B slides between the boards 22 and the angle irons 19. A cross brace 30 is secured to the boards 21 which form cleats and extends across the rear wall B. A brace tie rod 31 is secured to the ends of the bar 30 through the upper corners of the rear wall and secured to intermediate portions of the angle iron 16 and are fastened at 33 to the ends of the cross bar 11.

It will be seen that a load ofgravel is placed between the walls AA and B so that as the apparatus is dragged along the gravel is spread along the road escaping under the blade 29 the desired thickness on the 5 road depending upon the adjustment of the spreading beam B. I

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacriicing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A gravel spreader of the class described comprising a pair of spacedsparallel coextensive runners, side walls rising from the runners, a rear wall between the rear ends of the side walls, angle arms arranged on the inner sides of the side walls adjacent the rear wall, a beam movable between the angle arms and the rear wall, brackets on the rear walls, brackets rising from the beam, rods swivelled in said bracket rising from the beam and threaded through the brackets on the rear wall.

2. A gravel spreader of the class described comprising a pair of spaced parallel coeX- tensive runners, side Walls rising from the runners, a rear wall between the rear ends of the side walls, angle arms arranged on the innet sides of the side walls adjacent the rear wall, a beam movable between the angle arms and the rear wall, bracketson the rear walls, brackets rising from the beam, rods swivelled in said bracket rising from the beam and threaded through the brackets on the rear wall, the upper ends of said rods being in the form of cranks.

3. A gravel spreader of the class described comprising a vp'air'ot spaced parallel coextensive runners, side walls rising from the runners, a rear wall between the rear ends of the side walls, angle arms arranged on the inner sides of the side walls adjacent the rear wall, a beam movable between theangl'e arms and the rear wall, brackets on the rear walls, brackets rising from the beam, rods swivelled in said bracket rising from the beam and threaded through the brackets on the rear wall, the upper ends of said rods being in the form of cranks, therlower edge of said beam being arcuate and bowed upwardly 4:. A gravel spreader of the class described comprising a pair of spaced parallel coextensive runners, side walls rising from the runners, a rear wall between the rear ends of the side walls, angle arms arranged on the inner sides ofthe side walls adjacent the rear wall, a beam movable between the angle arms and the rear wall, brackets on the rear walls, brackets rising from the beam, rods swivelled in said bracket rising from the beam and In testimony whereof I afiiX my signature.
